The Milwaukee’s famed “Olympian,” powered by a
Baldwin-Westinghouse electric locomotive, is shown at Eagle Nest Tunnel in
Montana Canyon (near Ringling) in 1939. The complete absence of smoke and
cinders on the railroad’s electrified districts made it possible for
passengers to enjoy the luxury of riding in open observation cars through
the grandeur of mountain scenery along the route.
